Wireless Weather Wizard III

WIRELESS WEATHER WIZARD III ® STATIONThe Wireless Weather Wizard III station is comprised of two components: the sensorarray which houses and manages the external sensors; and the console which providesA/D conversion, calculations, and data display. The transmission of data betweenthe sensor array and the console is completely wireless; it uses an FCC-certified,license-free transmitter and receiver. User-selectable ID codes allow up to eightstations to coexist in the same geographic area. The stations is available in twoversions: one version’s sensor array is powered by a solar panel; the other’s, by a DCpoweradapter or lithium battery. Both versions include a DC-power adapter to power the console. AWeatherLInk may be added to this station for data logging and communication with a computer.S PECIFICATIONS7425WSTATIONSGeneralConsole Operating Temperature . . . . . . . . . . . . . . . . . . -5° to 140° F (-20° to 60° C)Display Temperature . . . . . . . . . . . . . . . . . . . . . . . . . 32° to 140° F (0° to 60° C)Sensor Array Operating Temperature . . . . . . . . . . . . . . -40° to 140° F (-40° to 60° C)Console Power Supply . . . . . . . . . . . . . . . . . . . . . . . . . . 30 mA (typical) at 10 to 16 VDC (125 mA when display is illuminated)Sensor Array Power RequirementsOptions. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6-12 VDC power adapter, CR-123 Lithium Battery, or Davis Solar ChargerConsumption. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 120 µABattery Life. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
